Increase screen updates

I´m trying to increasing screen updates. In a network with a firewall, a server, my pc (Win 2000 SP4, Pentium 3, 600MHz, 392M Ram) is conected to the server. I conect it to an external Pc, Pentium 4, 2.8GHz, 512M Ram, in XP. Telephon line is ADSL 256Kb. I change from colors configuration, max. screen updates/sec=30 but number of screen updates is 8 more of less. I conected it to the server and ¡¡¡ there are 98 screen updates/sec!!!

Ok, it is possible there are some bottlenecks . How can I send information in other way, other route, without bottlenecks Is it possible send information in other way with radmin Is it possible send information in a way without bottlenecks all time Thanks a lot
